LOL, Newsflash: I am also free to post opinions and I just did!
BTW you never did explain the relationship of your equation too the opening post regarding ramp orientation! Would that be because it is actually irrelevant to the opening post?
Here is your idea from a factual standpoint: In all of your musings you have yet to produce any evidence of relevance, nothing more than speculation with no supporting evidence. Since I am a real big fan of physical evidence, do you have any actual physical evidence other than a common 4.6 degree slope of the ramps? I know you have irrelevant equations supposedly supporting, what I consider to be, your improbable and totally unsupported fantasy musings.
What does become increasingly clear you know little or nothing of Ancient Egypt, so you attempt to cram their accomplishments into what you do know, while ignoring the available evidence as clues to what they actually did! The Ancient Egyptian thought processes are contained within their system of mathematics, the universal language.
Run your idea of funiculars by these guys, here: [http] or or here: [www.unexplained-mysteries.com]
I am sure you have many more smart-ass comments to bestow on anyone who has the audacity to question your methods and musings.
